CVE-2022-48699: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: sched/debug: fix dentry leak in update_sched_domain_debugfs Kuyo reports that the pattern of using debugfs_remove(debugfs_lookup()) leaks a dentry and with a hotplug stress test, the machine eventually runs out of memory. Fix this up by using the newly created debugfs_lookup_and_remove() call instead which properly handles the dentry reference counting logic.

Affected products

• Linux Linux Kernel: from 5.13, before 5.15.68 (fixed in 5.15.68); from 5.16, before 5.19.9 (fixed in 5.19.9); version 6.0 only
